However, there was a slightly synergistic effect of the combination of apigenin and imatinib at half of the I[C.sub.50] values (Api: 70, Im: 2.5 [micro]M), and a strong antagonistic effect
was observed when apigenin was decreased to 35 [micro]M.
(2013) found an antagonistic effect
for the control of Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae).
Sodium ions present in the growth mediums showed antagonistic effect
on calcium and potassium ions.
The fractional inhibitory concentration indices (FICI) were calculated for each of the paired antibiotics and were interpreted as [less than or equal to] 0.5 = synergistic, 0.5-[less than or equal to]1.0 = additive effect, >1-4 = no interaction, and [greater than or equal to] 4 antagonistic effect
Because of its antagonistic effect
on N-methyl-Daspartate (NMDA) receptors and its role in the regulation of calcium influx into the cell, magnesium sulfate (MgS) seems to have a potential analgesic effect when used as an adjuvant in FNB [6-10].
Another possible explanation for the persistent bacteremia in our patient may be a theoretical antagonistic effect
between ampicillin and vancomycin; this phenomenon is inconsistent in the literature, however, with uncertain clinical significance .
In in vitro test, antagonistic effect
of the three Trichoderma species against C.
Actually, an antagonistic effect
subsists between Na+ and beneficial ions (K+ and Ca2+) (Unlukara et al., 2010; Farooq et al., 2015), under this influence Na+ inhibits the entry of essential ions from soil solution to the roots, resulting in the reduction of these ions in plant leaves.
of Malaysian isolates of Trichoderma harzianum and Gliocladiwn virens on Sclerotium rolfsii".
In addition, it has a potent antagonistic effect
on serotonergic receptor subtypes 5-HT2B, 5-HT2C, 5-HT6 and 5-HT7, adrenergic receptor subtypes [alpha]1A, [alpha]2A, [alpha]2B,[alpha]a2C, and dopaminergic receptor subtypes D3 and D4.
Their antagonistic effect
in vitro on Fom and their potential on biocontrol agents in growth chamber was also studied.
